Hey all,
I have to bump this thread.. I have the symptoms of a blown head gasket, E.G. Bubbles in over flow tank But the bubbles only occur after boosting hard for a couple of times. I have tried flushing my coolant, changing to new radiator caps, 1.1 bar cap (with wings) top tank, 1.3 bar cap (round cap) on radiator itself, removing thermostat, but to no avail.. The thing is, this only happens after boosting hard. I was NOT overheating at all. The coolant seems to be pushed from the TOP tank to the overflow tank, after the overflow tank overflows, I open up the TOP tank and its significantly low in coolant or empty. My motor is a bone stock JDM EJ20 motor running a Twin Scroll VF turbo at 23psi I also bought the UVIEW combustion test kit and have tested extensively, when idling when revving, but the test comes up negative.. I should also mention that this came about coincidentally after my recent build which included, Turbo change (VF53 ball bearing) Downpipe change Timing belt / water pump change IAG TGV deletes Top feed rails with FIC injectors intercooler change Could any of these have affected and cause this problem?? Maybe its the turbo?? Could the water lines have been jammed up and cause lots of pressure in the TOP coolant tank, causing it to overflow to the overflow tank?? I have run out of ideas!!! Why wouldnt the test liquid just change to green??

What color is the coolant that is coming out? Also, what head studs did you build your motor with?
